将由胰脏提取分离的RNA制成注射液并注射在家兔、小鼠和狗等正常动物体内,观察了几种生理指标和病理组织学变化.结果表明,长期注射胰RNA的家兔其血清总蛋白含量和体重比对照组明显增高,而未发现任何不良反应,光镜下病理组织学检查未发现病理组织学异常变化.将1000倍的大剂量胰RNA注射在小鼠静脉内也未发现异常反应.对麻醉犬静脉注射胰RNA5mg/kg后,观察犬的血压、心率、呼吸,并未发现异常变化;犬肝动脉内注射胰RNA0.5mg/kg,对肝血流、血压、心率以及呼吸都无影响. RNA extracted from the pancreas was injected and injected into normal animals such as rabbits, mice, and dogs. Several physiological parameters and histopathological changes were observed. The results showed that rabbits that had long-term injection of pancreatic RNA had serum The total protein content and body weight were significantly higher than those in the control group, and no adverse reactions were found. Histopathological histology under light microscopy revealed no abnormal histopathological changes. No injection of 1000-fold high-dose pancreatic RNA into the mouse vein was found. Abnormal reaction. After anesthetized dogs were intravenously injected with 5mg/kg of pancreatic RNA, the dog’s blood pressure, heart rate, and respiration were observed. No abnormal changes were observed. Dogs received intrahepatic arterial injection of 0.5 mg/kg pancreatic RNA for hepatic blood flow, blood pressure, and heart rate. Breathing has no effect.
